Abstract
Oral dysfunction due to peri-implantitis and shortened life of implants has become a major concern. Self-care and removal of oral biofilms by professional mechanical tooth cleaning (PMTC) are indispensable for its prevention. However, if the surface roughness of the implant is increased, it may result in the adhesion of biofilm in the oral cavity. Therefore, the PMTC method can serve for long-term implant management. Calcium carbonate (CaCO3) has been used as a cleaning method for implant surfaces; however, there is concern that the implant surface roughness could increase due to particle collision. Therefore, in this study, to establish a blasting cleaning method that does not adversely affect the implant surface, a new blasting cleaning method using agar particles was devised and its practical application examined. When the simulated stains were blasted with white alumina (WA) abrasive grains and CaCO3 particles, the simulated stains were almost removed, the surface roughness changed to a satin-finished surface—which was thought to be due to fine scratches—and the surface roughness increased. Most of the simulated stains were removed on the surface of the sample blasted with glycine particles and agar particles. Conversely, the gloss of the sample surface was maintained after cleaning, and the increase in surface roughness was slight.

This study aimed to develop a professional mechanical tooth cleaning (PMTC) method for treating peri-implantitis by applying various particles using blasting equipment, regardless of the skill of dentists and dental hygienists
The following conclusions were obtained as a result of blasting using multiple particles to develop a new PMTC that can be performed regardless of the skill of the dentist without damaging the implant surface
Summary
Implant treatment is an indispensable option for the prosthetic treatment of tooth defects, and patients’ need for this treatment is very high [1,2]. Pure titanium and titanium alloys are the main implant materials used. Titanium surfaces are biocompatible and have excellent mechanical properties, and when implanted in a living body, cause osseointegration with bone, making it useful as a biomaterial. Unlike natural peri-dental soft tissue, the peri-implant soft tissue does not have a sealing structure and is fragile. The mucosa around the implant has a high risk of infection. If inflammation occurs around the implant, the spread of inflammation is much faster than with natural teeth, and the risk of peri-implantitis and the implant itself falling off is very high [3,4,5]
